SummaryNX™ Advanced Thermal software extends the modeling and simulation capabilities of NX Thermal or NX Electronic Systems Cooling. NX Advanced Thermal provides a wide range of methods for advanced radia-tion analysis, radiative and electrical heating models, advanced materials mod-els such as phase change, charring and ablation, as well as one-dimensional hydraulic network modeling. Thermo-fluid coupling is enabled with NX Flow and NX Advanced Flow, and thermo-elastic effects can be simulated by mapping temperature results to NX Nastran® software.

NX Advanced Thermal continues Siemens’ long heritage in ther-mal simulation and leverages the same technology that under-pinned the I-deas™ TMG solution. NX Advanced Thermal adds a rich feature set to the powerful

simulation technology of NX Thermal. Intended for tackling complex thermal physics and challenging thermal manage-ment problems, NX Advanced Thermal offers the same best-in-class level of inte-gration within the NX preprocessing, postprocessing and simulation tools.

Applications of NX Advanced Thermal include simulation and analysis of a range of heat transfer problems in aerospace, automotive, electronics, power, process and other industries. NX Advanced Thermal offers the following additional features on top of the NX Thermal license.

NX Advanced Thermal

NX

Multiphysics environment supportNX Advanced Thermal enables the multi-physics environment to solve thermo-mechanical problems in loosely (one-way) or tightly-coupled (two-way) modes.

This environment delivers a consistent look and feel for performing multiphysics simula tions so you can easily build coupled solutions on the same mesh using common element types, properties, boundary condi-tions, as well as solver controls and options.

Coupled thermal-structural analysis enables you to leverage the NX Nastran SOL 401 multi-step nonlinear solver and a thermal solution from the NX Thermal solver.

Open architecture• Full access to thermal system equations

• Incorporation of external models

• Enhanced solution control

• User subroutines for integration of custom code in the solution sequence

Parallelized radiation solver• Parallel view factor calculations and

flexible thermal solver multi-threading based on the number of available cores for solution efficiency

• The NX Advanced Thermal product includes access to up to 8 cores on one machine for the supported solver modules

• The available NX Thermal/Flow DMP add-on removes any software limitations on the number of cores and enables network and cluster support

• Distributed memory (MPI) based parallelization for highly scalable computation of view factors and radiative heating – available with the NX Thermal/Flow DMP add-on

Supported hardware/OSNX Advanced Thermal is an add-on module to either NX Advanced FEM or NX Advanced Simulation. It requires a license of NX Thermal as a prerequisite. All stan-dard NX hardware/OS platforms are supported (including Windows, Linux and selected 64-bit platforms). Contact Siemens PLM Software for any other specific hard-ware/OS support requests.
